1Can the M2 Max and GeForce RTX 4090 run Rust well?
The M2 Max and GeForce RTX 4090 will struggle to run Rust at smooth framerates.
A true test for system memory. Procedural maps can exhaust RAM quickly; 16GB is the minimum, and 32GB is recommended. CPUs with 3D V-Cache (AMD X3D) offer massive performance gains here.
Performance Report
The GeForce RTX 4090 is 244% above the recommended GPU (GeForce GTX 980) for Rust. The M2 Max is 119% above the recommended CPU (Core i7-4790K).
No major FPS-ceiling mismatch detected. The GeForce RTX 4090 and M2 Max stay close in effective frame-generation ceiling across the tested resolutions and quality settings.

The M2 Max + GeForce RTX 4090 pairing runs this title with CPU utilization between 23% and 47% and GPU utilization between 67% and 96%. M2 Max keeps significant headroom across presets, while GeForce RTX 4090 carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 75% at 1080p to 88% at 4K, while CPU averages move from 30% to 29%.
From a utilization perspective, this is a GPU-heavy load profile. At 4K (Ultra HD) High, the GeForce RTX 4090 averages 92% usage (89-96%), while the M2 Max stays at 27% (23-31%). This shows the graphics pipeline is carrying most of the workload, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 30% and GPU 75%. At 1440p, that shifts to CPU 30% and GPU 76%, and at 4K it reaches CPU 29% and GPU 88%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Medium is the most balanced preset based on this dataset. It runs around CPU 28% (23-32%) and GPU 85% (78-92%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while M2 Max remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the M2 Max and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

The M2 Max and GeForce RTX 4090 will struggle to run Rust at smooth framerates.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
This setup is already well-balanced for Rust. No significant bottleneck - CPU and GPU are well matched across all settings. Both the M2 Max and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
Rust does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Rust requires at minimum a Core i7-3770 (CPU) and GeForce GTX 670 (GPU) with 10 GB RAM and 25 GB (SSD) storage. For the recommended experience, you need a Core i7-4790K and GeForce GTX 980 with 16 GB RAM. Your M2 Max and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Rust FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
